18. A. constrictus, Fr. (white rneal-scenfed Agaric) ; pileiis

 stem solid nearly equal, ring very narrow. Fr, Syst. Myc. v,

In a meadow, on a spot bleached and scorched by cow-dung, (in moist 

 places in grass scorched by horse urine. F>. /. c.) and in the path of a 

 wood in a tuft of grass amongst which lay the bones of a rabbit. Sept. — 

 Oct. Woodnewton. King's Cliffe, Northamptonshire. liev. M. J. Ber- 

 keley. — Pure white. P'llevs obtuse, plano-convex, broadly umbonate, 

 fleshy, shining with a silky lustre like A. prunulus ; w hen bruised, it 

 assumes a very pale yellow tint. Gills close, very deeply emarginate, even 

 when quite young. " Sporules white, subelliptic. Slem 2 inches high, ^ 

 of an inch thick, rather flexuous, fibrillose, solid, but the substance 

 within more lax and fibrillose, though not eminently so, very brittle. 

 When young there is a delicate web-like curtain, but this soon vanishes. 

 Odour very strong, like that of fresh flour. — This agrees so exactly in 

 every point but one with the description of A. constrictus in Fries' Elen- 

 chus, that I cannot persuade myself that it is different, though my 

 specimens, as regards the veil, seem rather to point to Tricholoma than 

 Armillaria. There is, however, no species of Trichoioma with which it 

 at all accords ; and as the veil is more subject to vary than almost any 

 other part of an Agaric, I venture, in the absence of any figure, to con- 

 sider my plant as the same with that of Fries. 1 am the more confirmed 

 in doing so, because in thousands of specimens of A. fastibilis, even in 

 the youngest stage of growth, I have never been able to see the least 

 trace of a veil, though Fries assigns it, and Schoeffer figures a distinct 

 one. 



19. A. mucidus, Schrad. (musty Agaric); more or less tufted, 

 pileus thin glutinous, gills distant adnexed, stem bulbous, ring 

 sulcate superior reflexed and then erect. Schrad. Spic. p. 116.

On trunks and sticks, especially of beech. The Rookery, Dorking, 

 Oct. 9, 1828. — Gregarious, caespitose. F i leiis \h \uch broad, (1—5, 

 Fr.) white tinged with brown, hemispherical, clammy, uneven, radiato- 

 rugose, tough, margin thin somewhat turned in. Gills broad distant 

 rounded behind, but not in front, adnate, margin serrulate. Stem 

 l^—ii inches high, 1 — 2 lines thick, bulbous, attenuated upwards often 

 curved, white, brown at the base where it has very minute adprcssed 

 scales, juicy, composed of fibres, solid, with a pale line down the centre. 

 Ring persistent, the margin often brown and slimy conijiosed as it were 

 of two coats the one arising from the sciuamula*, the other from the real 

 epidermis of the stem. Fries describes the ring as superior, deHexed 

 but close, and then again erect. But it adheres so closely to the stem 

 by its upper portion as very easily to escape notice in an ailvanced stage 

 of growth : when yotuig before the expansion of the pileus, the little 

 channel is visii)le between the ring and stem. 



20. A. milieus, \M. (Uack-scaled Agaric); tufted, pileus 

 dirty yellow, rough witli black hairy scales, gills distant
